Sister’s Trick

“But I CAN’T have sex with my own Brother!” Marcia’s
objection SOUNDED reasonable enough . . . unless you knew that
the four of us were stark-naked, and had been “fooling around”
with each other for over two hours. Both Marcia and I had sucked
BOTH guys off twice in that time; never bothering to even care if
the guy’s prick squirting thick white baby-juice against our
tonsils was our sibling’s, or our boyfriend’s. The four of us
have been getting into and out of trouble together for longer
than I can remember. Once we reached puberty though, things had
rapidly progressed from just kisses and hugs, to our present
involvement, where nothing was off-base except doing “the real
thing”, and Mike and I were working to remove that last barrier.
Marcia always was the naive one of the group though, and I
figured it was up to me to get the little girl ALL the way into
what Mike and I had started about a week ago, when it was too
snowy to leave the house. Only I planned on a little “surprise”
for Marcia that she didn’t expect.
For once, my cute little cousin would be FIRST in doing
something, instead of me. Only she just didn’t know it yet.
Even Dan was in on it, though it had taken the threat of watching
me and Mike “get it on”, while he only got to watch, to bring him
around. Still, I had only sucked him off twice since then;
telling him he wasn’t fucking ME, until he did it “properly” with
his little sister. I guess seeing Mike’s prick sliding up in my
seemingly bare cunny; squeezing on my brother’s prick like no
hand or even mouth COULD do, convinced him.

“Why not?” asked Dan. “Mike and Sherry do!”
Marcia didn’t even bother to look at us to see if we agreed
with her brother. I guess she knew the ring of truth when she
heard it. Besides, it sounded just like something we WOULD do
(and had too).
Abandoning THAT line of defense, our little cousin blurted
out the thing that really bothered her “But what if I get
pregnant?” she almost wailed; seeming to be more worried about
NOT being able to have sex with her big brother, like I was, than
at the prospect of having his baby in her belly.
